Claims priority, application Switzerland October 8, 1954 4 Claims. (Cl.28-1) There are various hand apparatus which have to be continuallyreciprocated by the user, thus tiring his hand, wrist and arm.

Let us take as an example the marking apparatus which is frequently usedin the textile industry, and with which marks in the form of threads areapplied to the edge of a continuously moving fabric. Apparatus of thistype often weigh 750 grams and not only must they be held, advanced andwithdrawn by hand at the correct height in relation to the fabric edge,but in addition to their actual operation they demand the expenditure ofstill more effort every time the marking thread has to be applied andknotted.

To make this work easier and to relieve the hand of the personperforming it, the present invention envisages the incorporation of areciprocatable slide in a rectilinear guide, which slide possesses meansto hold the hand apparatus concerned.

This extremely simple solution, which relieves the hand of the apparatusweight, can be supplemented by making electrically or pneumaticallycontrolled members operate the advance and withdrawal of the slidetogether with the hand apparatus, or operate the said apparatusautomatically.

The attached drawing shows two typical embodiments of the object of theinvention.

Fig. 1 illustrates the attachment according to the first embodiment,without separate drive.

Fig. 2 shows the same attachment with the hand apparatus mounted on it.

Fig. 3 is a longitudinal section, showing the positions occupied by thehand apparatus in use.

Figs. 4 to 6 are two illustrations and one section respectively andrefer to the second embodiment with an electro-magnetic drive.

The attachment according to the first embodiment, which is illustratedin Fig. 1 and the perspective of which is inclined forwards a little inorder to reveal the inside more clearly, consists of a sheet metal,through-like, profiled guide 1 in which a suitable profiled plate 2,designed as a slide, can reciprocate in a longitudinal direction.

This plate has a hook 3 and a clamp 4 which serve to hold apredetermined hand apparatus and must in every case be adapted to theapparatus concerned.

The guide 1 may be attached to a base of its own, or also to a suitablepart of e. g. a cloth examining machine or a loom.

Fig. 2 shows how a hand apparatus 5 can be mounted on the clamping slideand advanced or withdrawn together with the latter in the direction ofthe arrows 6 and 7 respectively.

The hand apparatus illustrated corresponds to the marking apparatusalready mentioned as an example and serves to arrange threads on theedge 8 of a fabric which moves past the user in the direction of arrow 9and has to be checked.

To mark this edge, the apparatus 5 is advanced in the direction of arrow6 until the edge 8 of the fabric enters the opening 11 in the apparatus,whereupon apiece of thread is applied and knotted by pressing thedownwardly swivelable lever 13 in the direction of arrow 12.

Whenv the mark has been made, the apparatus is with drawn in thedirection of arrow 7 until it releases the web of material.

The section illustrated in Fig. 3 clearly shows these two positions, i.e. the withdrawn rest position 5' (unbroken line) and the advancedoperative position 5 (broken line). In the latter position it can easilybe seen how the fabric 10 has penetrated the opening 11 in theapparatus.

The user is thus enabled to mark the fabric without having to lift theapparatus; also, he is completely relieved of the need to make sure thatthe edge of the material enters the apparatus in a flawless manner. Allhe has to do is to slide the apparatus to and fro, which requires noeffort, and merely to exert pressure on it every time, helped by theweight of his own hand.

In the case of the second embodiment, according to Figs. 4 to 6, a guide14 similar to the guide 1 in the first embodiment is used and is securedto a box 15 which ispartly visible in Figs. 4 and 5 and contains theoperating mechanism.

The slide on profiled plate 17 holding the hand apparatus 16 (see Fig.5) and fitted to guide 1 is also similar to the one described inconnection with the first embodiment; the only difference is that thisslide or plate 17 has two holes through which the two legs of a stirrup18 are passed.

This stirrup is designed to be placed round the hand apparatus and isoperated from below in such a manner as to press the lever 19 downwards.

Arranged for this purpose in the box 15 is an electromagnet 20 with acore 21 (lower half in section), which latter tensions via cord 22 androller 23 the spring secured to the box wall. At the same time thespring serves to withdraw the core 21 into the rest positionillustrated.

The spring and cord act on the bottom free end of a lever 26 which isflexibly attached to the slide or plate 17 and projects into the boxthrough an opening 25 in the bottom of the guide 14.

Normally and in respect of the advance direction 27 of the slide thislever is swivelled to the rear and is locked in this position by thestirrup 18 flexibly attached to the said slide or plate 17. The stirrupitself, as already stated, is supported on the operating lever 19 of thehand apparatus selected by way of example, which therefore opposes aresistance to the dropping of the stirrup.

If the electromagnet is excited, it withdraws the core 21, whereby theslide or plate 17 is first advanced into position 17' and the lever 26into the parallel position 26. The spring 24 is tensioned accordingly.

The lug 29, however, to which the lever 26 is flexibly attached, bearsagainst the edge of the lower guide opening 25 before the core 21 hascompleted its working stroke. Additional tension on the cord 22 finallycauses the lever 26 to be swivelled into position 26", which results inthe stirrup 18 being drawn downwards into position 18'.

This lattter movement actuates the lever 19 which is swivelled towards19'.

If the attachment is suitably positioned to bring the hand apparatusinto operative, or marking connection with a fabric when the slide orplate 17 is advanced, it can easily be seen that the apparatus advancedby the core of the electromagnet will grip the edge of the fabric andthen apply the desired mark.

When the current is interrupted, the spring 24 Withate flisuae a plate17 together with the hand appara- "tus' into -'the' startin'gposition'illustrated' Instead of being operated electrically, anattachment of thistype could betoperatedpneumatically. ,For this Ipurpose, the electromagnet merely needs to'be. replaced by a cylinderand piston, the piston playing the part of'the tachment could be usedto, operate a counter which would record the attachments every function.V

It is also feasible to arrange several attachments according to theinvention s'ideby side or to form, them into a combined unit, e. g. .forthe purpose of marking a fabric with different colours, depending onwhich handapparatus issetinoperation. '1 l '1.
